When you are in Tomorrow view and add a new task, by default the option for "all-day" is selected. If you deselect the option the date changes to one day forward. So you accidentally create a task for day after tomorrow instead.

I have tested this by clicking new task and selecting / unselecting "all-day". As many times you click it, it keeps adding one day to the date. I have clicked it a few times and am attaching an image with Tomorrow showing as 2014-10-14

The web view works fine.
